# Generic Makefile for Ocaml projects
# Written by necula@cs.berkeley.edu
#
# Features:
# - keeps byproducts of building in a separate directory
# - handles dependencies automatically
# - user specifies just what modules go into a project and
# everything else is done automatically
# - you can use one Makefile for several Ocaml projects
#
# You must include this file in your Makefile. Before the include point
# you must defined the following variables (which are glob al for all Ocaml
# projects specified in one Makefile):
#
# OBJDIR - the directory where to put all object files. This directory
# must exist (default obj)
# DEPENDDIR - the directory where to put dependency files. This directory
# must exist. (default obj/.depend)
# NATIVECAML - if set then will use the native compiler
# UNSAFE - if set then will turn off safety checks (only with NATIVECAML)
# MODULES - a list of all modules for all projects defined in the
# Makefile. Give only the basenames (no directory,
# no extension). This is used to create the dependencies.
# SOURCEDIRS - a list of all directories containing sources for all
# projects defined in a Makefile. This is used to set vpath.
# MLLS - a list of all .mll (ocamllex input) files for all
# projects defined in the Makefile.
# MLYS - a list of all .mly (ocamlyacc input) files for all
# projects defined in the Makefile.
# ECHO - if specifically set to nothing then it will print
# all of the commands issued. Set this in the command line
# if you want to see what is going on.
#
# After you set all of the above you must do the following for EACH separate
# executable that you want to build.
#
# Define the following:
# PROJECT_EXECUTABLE - the name of the executable you want to build. To take
# advantage of the naming scheme that separates the
# bytecode version and the native version, use the
# $(EXE) variable which is defined to either .byte.exe
# or .asm.exe. I typically put the executable in
# $(OBJDIR) as well.
# PROJECT_MODULES - the base names of the modules that make this
# executable in the order in which they must be
# passed to the linker. Make sure that all of
# the names mentioned here are also mentioned in
# MODULES.
# PROJECT_CMODULES - same as modules but for the C modules. These
# do not need to be mentioned in MODULES
# PROJECT_LIBS - the base names of the libraries that you
# want to link in the executable.
#
#
# Then include Makefile.ocaml.build to generate a customized
# rule for making your executable.
#
# Example:
#
# OBJDIR = obj
# DEPENDDIR = obj/.depend
# SOURCEDIRS = src src/special
# MLLS = mylex
# MLYS = myparse
#
# MODULES = mod11 mod12 mod21 modcommon
#
# # Rules for project 1
# PROJECT_EXECUTABLE = $(OBJDIR)/proj1$(EXE)
# PROJECT_MODULES = mod11 mod12 modcommon
# PROJECT_CMODULES =
# PROJEC_LIBS = unix
# include Makefile.ocaml.build
#
#
# # Rules for project 2
# PROJECT_EXECUTABLE = $(OBJDIR)/proj2$(EXE)
# PROJECT_MODULES = mod21 modcommon
# PROJECT_CMODULES =
# PROJEC_LIBS = unix str
# include Makefile.ocaml.build

# sm: two styles for echoing compilation progress:
# style 1, by George:
# - print English descriptions of what's happening
# - set ECHO to "" to see *everything*
# style 2, by Scott:
# - do not print English descriptions
# - print every shell command that is executed which has a side effect,
# so that they could be pasted into a shell to reproduce manually
# - omit some of the details of dependency generation
#
# to be able to choose which style, several variables are used:
# @$(NARRATIVE) - put this before English descriptions for style 1
# @$(COMMAND) - put this before shell commands which are to be
# printed for style 2; the command is *not* executed
# $(AT) - put this before shell commands which are to be executed,
# and also printed in style 2
# $(ECHO) - use in place of '@' for things not printed in either style
